tcp: move tcp_do_parse_auth_options() to net/ipv4/tcp.c

tcp_do_parse_auth_options() fast path user is tcp_inbound_hash().

Move tcp_do_parse_auth_options() right before tcp_inbound_hash()
so that it can be (auto)inlined by the compiler.

As a bonus, stack canary is removed from tcp_inbound_hash().

Also use EXPORT_IPV6_MOD(tcp_do_parse_auth_options).
